The heritability of some traits and behaviors is subject to change over the lifetime because of the decaying effect of shared environment [ 43– 45], and because of some life events that may or may not lead to gene environment interactions.
Diseases were on the rise because of the decaying healthcare system.
Because of decaying nature of integrand with respect to wave number k, the numerical integration can only be performed up to a certain upper limit ku instead of ∞ without loosing accuracy.
Although 90Y is predominantly a β− emitter, coincidence imaging of 90Y is possible because of a minor decay branch to the 0+ first excited state of zirconium-90 followed by β−β+ internal pair production at a very low branching ratio of 31.86 ± 0.47 × 10−6 [210−6].
When fluorescein sodium solution was instilled into the eye, fluorescence intensity was measured every minute for 10 min. When DAF emulsion was instilled, measurements were repeated every 5 min for 50 min because of a slower decay of intensity.
On the other hand, the soil may actually become more permeable after some time because of decaying wood providing passage for the escape of water or because of increasing biological activity (roots, animals) or the formation of cracks.
Bill Collier, a friend of Ann's who arrived in Indonesia in 1968 and spent 15 years doing social and economic surveys in villages, told me that researchers were told by people living near brackish waterways that they had been unable to eat the fish because of decaying corpses in the water.
Because radon has a similar pressure and temperature curve to propane, and oil refineries separate petrochemicals based on their boiling points, the piping carrying freshly separated propane in oil refineries can become radioactive because of decaying radon and its products.
This method was necessary as the previous method used to synthesize transuranic elements, neutron capture, could not work because of a lack of beta decaying isotopes of fermium that would produce isotopes of the next element, mendelevium, and also due to the very short half-life to spontaneous fission of fermium-258 that thus constituted a hard limit to the success of the neutron capture process.
Furthermore, introgression experiments revealed that the propensity for cured asexual females to produce only sons (because of decayed sexual attractiveness, mating behavior and/or egg fertilization) is likely caused by recessive genetic effects at a single locus.
